A New Canaan woman accused of harassing her then-boyfriend's daughter by posting parts of the girl's private journals online in 2010 was found guilty of second-degree harassment and second-degree breach of peace at state Superior Court in Norwalk on Friday.

Terri Buhl, 40, was acquitted of the most severe charge interfering with a police investigation.

Buhl was charged in November 2010 after New Canaan police determined she posted parts of the 17-year-old's personal journal, detailing underage drinking and sexual activity at a party on Facebook.

She could face a maximum of nine months in prison and a $1,500 fine. Buhl plans on appealing the verdict, Frank DiScala, her attorney said.

According to the prosecution argument, Buhl created a Facebook account under the alias "Tasha Moore" onto which she posted photographs of diary entries of the New Canaan High School senior. Buhl was dating the girl's father at the time. The diary entries had been stuffed in the back of the girl's bedside drawer.

The prosecuting attorney, Donna Krusinski, attempted to show the IP address attached to the Facebook posts was the same as Buhl's IP address, but the defense noted there was no documentation from Facebook submitted for the record.

Judge William Wenzel said that since Buhl was the only one known to have had possession of the diary entries, and since all of the school's seniors were at graduation during the time the posts in question were made, that could be seen as evidence enough of her culpability.

The defense argued that Buhl had a good relationship with the girl and her father and she therefore had no motive to post the embarrassing diary entries, citing the statute's language of intent to harass or annoy.

During a court recess, Buhl said she was using the diary entries, which she claimed had been given to her by one of the girl's peers, for an investigative piece on adult-sponsored teen drinking parties in New Canaan, which she said she still plans on publishing.

The prosecution made the argument that the actions could have no other intent than to harass and annoy, so if Buhl committed the actions, that's what she must have wanted.

The prosecution's argument, that Buhl's only statement to police, "I am Teri Buhl, not Tasha Moore," constituted a misleading statement that caused the police months and months of investigative work.

Wenzel said Buhl had the right not to speak and did so at her own peril, but also noted that she is not, in fact, Tasha Moore, and asked if she had been asked if she posted under the pseudonym Tasha Moore. Indeed, she had not been asked that. He ruled she was not guilty on that charge.

Buhl's attorney said he was hoping for a better outcome.

"(The judge) got her on two of the three, which was a surprise," DiScala said. "He was a careful judge."

The family declined to comment after the trial, but Krusinski said she was happy with the result.

"I thought it was a fair verdict," she said. "In this day and age of social media, people can't hide behind it to harass families."
